0release is a program to generate source and binary releases automatically. With minimal configuration, 0release will generate a source tarball release candidate, build it to create a binary archive, upload them to your Web server, check the uploads, and tag the release in GIT and update the version number. It can run unit-tests and custom actions, such as building documentation, etc. For Zero Install users, it can also upload a signed XML metadata file about the release, allowing these users to upgrade automatically. Releases are signed with your GPG key.

The 64 Studio Platform Development Kit (PDK) is a
version control system for GNU/Linux
distributions, allowing the creation and
management of many different projects, based on
Debian and Ubuntu sources. PDK is written in
Python, and the source code is well commented and
contains documented examples.

The goal for A-A-P is to make it easy to locate,
download, and install software. Additionally, it
supports making changes to a program and managing
different versions that exist in the world, making
it useful both for users and for developers. It
uses a recipe that is similar to a Makefile, but
with many enhancements, such as integrated Python
script support, support for Internet access, and
version control. An IDE will be provided that
integrates your favorite editor, debugger, and
other tools.

Advisory Check is a program that reads security advisories for you. It gathers security advisories using RSS, RDF, or XML feeds, compares them against the installed software, and alerts you if you're vulnerable.
A wide variety of package managers can be queried to detect installed software. Remote systems can be monitored by using the integrated SSH, Windows-RPC, and Nmap support.

Alindis - A GNU/Linux Distribution is a comprehensive guide which leads the reader from zero to his/her own GNU/Linux distribution. In the course of the lecture, the reader will be able to reproduce the creation of the Alindis GNU/Linux distribution, the example implementation of the concepts shown there. The guide and the distribution together form the Alindis project.

The Ape Base Compile System is a set of scripts
that leverage ESP EPM and MREPO to maintain Red
Hat based systems that require custom and secluded
binaries. It achieves cross platform reproducible
compiles applications like Apache HTTPD, MySQL,
and PHP, supports a common --prefix parent
directory to allow different versions of an
application to be installed, provides an easy
method to switch between application versions,
places selected application binaries in a central
"bin" directory, supports delivery via Yum and
other common installers, and provides a method for
non-compiled "skeleton" files to be included with
installation and distribution.

Aphid (the Apache/Perl HTTP Installation Daemon) provides a quick facility for compiling and installing the Apache Web server with support for SSL via mod_ssl, and with the embedded Perl interpreter provided by mod_perl. It downloads, compiles, and installs the software into the directory of your choice. Aphid places emphasis on providing an intuitive, browser-based interface and keeping a tiny distribution footprint. To date Aphid has been tested on Rehat Linux 6 and 6.2, FreeBSD 4.0, and Solaris 2.6 and 7.

Apt-Cacher NG is a caching HTTP download proxy for
software packages, primarily for Debian/Ubuntu
clients. It's partially based on concepts of
Apt-Cacher but is rewritten with a main focus on
performance and low resource usage.
